Specification of Letters Patent.

Application filed November 19, 1914. Serial No. 872,945. h

To all whom it may concern:

Be it lmown that I, OWEN K. HARRY, citizen of theUnited States, residingat Dallas, in the county of Dallas and State of Texas, have inventedcertain new and useful Improvements in'Sheet-Metal Tanks, of which thefollowing is a specification.

This invention relates to new and useful improvements in sheet metaltanks.

The object of the invention is to provide a sheet metal'tank comprisingessentially upright outside supporting members or studs and sheet metalsections arranged in courses and seamed together, the stud being notchedto receive the seams of the sections.

Another object is to assemble the studs and sections either in acircular structure or one having angles and corners and in the lattercase to provide a reinforced corner in each instance.

A further feature resides in the provision of a sheathing for the tankwhereby a filler of concrete or other material may be used and acomposite wall had.

feed, grain or any other commodity, perishable or imperishable.

A still further object of the invention is to provide a tankconstruction that will be efiicient and durable, and in which theseveral parts will not be likely to get out of order or requireunreasonable repair.

With the above and other objects in view the invention'has relation tocertain novel features of constructlon and operation, an example ofwhichis descrlbed 1n the following specification and illustrated in theaccompanying drawings, wherein:

- Figure 1 is an elevation of the inventlonin the form of a silo, aportion of the base bein shown in section, Fig. 2 is a sectional detailof the seam joint between the sheet metal sections, Fig. 3 is ahorizontal cross sectional view taken on the line m-w.of Fig. 1, Fig. 4is a detail in vertical section showing one of the silo' doors, Flg. 5is a detail of a modified form of stud, Fig. 6 is a side elevation of acorn crib embodying this invention, Fig. 7 is an elevation of the same,

ehors secured to their lower ends. each comprise a pair of metal plates7 se- In the drawings the numeral 1 designates an outside verticalsupporting member or. stud of which several are employed and which Iprefer to construct of wood. The number of studs used depends upon thesize of the tank and the distance at which the studs are spaced. InFigs. 1 to 5 the studs are shown in connection with a cylindrical tank;while in the other figures the studs are employed with a rectangularstructure.

'Sheet metal sections 2 are arranged in courses and are nailed orotherwise secured to the-inner edges 'of the studs. As is best shown inFig. 2 the sections are connected by a seam joint. One'section has anoutwardly directed flange 3 along its lower edge; while the othersection hasan out standing folded flange 4 into which the flange 3extends, the flange 4:- being along the upper edge of its section.- Bypressing the flange 4 down on the flange 3 a tight seam or joint isformed. In order to make the seam air and water tight a"packing 5, isinterposed between the flanges within the flange 4 at each seam. In thecylindrical. tank the seams extend circumferentially in horizontalplanes and form external ribs which add materially to the strength andrigidity of the tank. It will be observed that the studs 1 fit flushwith the outer surface of the sheet metal sections 2 and the studs areprovided with notches or pockets 6 receiving the Patented Oct. 19,1915..

seams. The flanges 4 of the seams reston the bottoms of the notches'andare thus supported, The studs not only form upright supports and bracethe tank against the tank can neither buckle above its foundation orsink without carrying the studs with it.

As shown in Fig, l the studs project be- .low the lowermost section 2-and .have am These cured to the studs and depending therefrom. Ahorizontal metal bar 8 is passed through the lower ends of each pair ofplates and projects beyond the same. The anchors and lower ends of thestuds are embedded in a concrete base 9 which is dished out at 10 liemetal section.

, For reinforcing and insulating the tank a corrugated metal sheathing11 is disposed about the studs opposite the first section 2 whereby aplurality of vertical spaces are formed between the studs. These spacesmay be filled with concrete or sand or any other material desired. It isobvious that the sheathing may beextended upward as high as desired. v

As shown in Fig. 5 the studs 1 may each be formed of comparatively shortlengths 12 and 14 arranged in break-joint relation, one overlapping theother. Where a tank of considerable height is to be built, this form ofstud could be employed to obviate the use of long single piece studs.

The cylindrical tankjust described is intended to be used as a silo, butit is obvious that its use is not so limited and it may be used for amultiplicity of purposes. For

use as a silo it may be provided with a series of doors 15closing'doorways 16 as shown in Fig. 4. Each door is held against itsdoorway by a follower screw 17 mounted in a cross bar 18 supportediii-brackets 19 fastened on adjacent studs.

The door construction forms no parts of the invention and may be varied.

It is quite apparent that this invention may be applied to numerouskinds and forms of tanks and like structures. As another example I haveshown in Fig. 6, {and 8, a corn crib which comprises the same mainelements as the studs 1, sheet metal sections 2, and flanges 3 and 4.However in this case the'metal .sections are inverted so that theflanges 3 are on the upper edges and the flanges 4 on the lower edges.The studs also have the notches 6 for receiving and supporting theseams. By in verting theseams the open side is disposed underneath and asubstantially water tight jointis provided.

As shown the corncrib has a rectangular shape and at eachcorner a post20 is provided which takes the place of a stud at each side of the endsA. The sides B have the studs spaced in regular order and in assemblingthe crib the studs at each end of the sides are secured to the posts 20by bolts 21. A metal bottom 22 is dropped inside the crib and has anupstanding marginal flange 23 by which it is secured to the smooth metalwalls of the crib. The crib is supported on a base or platform made ofship-lap 24. A transversely curved corrugated roof 25 is held on thecrib by angle bars 26 secured to the inner walls of the sides B. At oneor both ends of the crib a pair of doors 2'? and 28 separated by a mullion 29, are provided for filling and emptying the crib. The samefeatures of strength and rigidity are present in this form as are foundin the cylindrical shape.

While ll have only shown two forms of structures I wish it understoodthat this invention is presented as including all forms, shapes, changesand modifications which may properly come within the scope of theappended claims.

What I claim, is:

1. The combination in a storage tank construction, of a plurality ofvertical studs having recesses cut in their inner edges, a plurality ofsheet metal sections arranged in. courses, each section having anoutstanding single flange along edge, and a folded outstanding flangealong the opposite edge of each section, the single flange of onesection engaging in the folded flange of the next adjacentsection, andthe folded flanges engaging in recesses of the studs, whereby eachcourse of sections is supported directly by the studs.

2. Tn a tank construction, the combination with a vertical wallcomprising a plurality of flange sections forming horizontal outstandingseams, of a plurality of vertical supporting studs having recesses cutin their-edges adjacent to each of the seams I and into which said seamsfit, whereby each of the sections .is supported directly by said studs.a

In testimony whereof I aflix my signav twowitnesses.
